摘要

Modulation of cellular processes critical to bone ingrowth could improve both short and long term titanium implant efficacy. The current study showed microencapsulation of TGFβ1 in PLGA and delivery up to 4 wks, increasing osteoprogenitor cell migration and proliferation. Furthermore, TGFβ1 may enhance in vivo bone ingrowth into macroporous implants as evidenced by fluorescence microscopy. Quantification of several static and dynamic histomorphometrical parameters is currently underway using our previous methods (Clark et al. 2005B). TGF-β1 release from hollow titanium implants could potentially be used clinically to accelerate bone ingrowth and improve implant efficacy.
